add Volume indicator for xUbuntu 16.04 LTS

Running xUbuntu 16.04 LTS on VMware.

I am a less is better person, so did no have sound card at begining.

After add sound card, found there is no Volume indicator on Panel as an option.

I am using pulseaudio server for sound in xUbuntu.

apt-get install xfce4-pulseaudio-plugin

Logout then Login.

Now you can add the Volume indicator on the Panel.

I spin an new Ubuntu VM.
Note 1: 32bit is easier because of no lib32gcc1 required.
Download SteamCMD.

cd ~/steamcmd

How to disable right-click on the desktop in Xfce 4.10

This is the second shoot on Xfce.

First my testing box:

  Fresh Install 12.04 32-bit.
  Then apt-get update, upgrade and dist-upgrade
  Then ppa upgrade xfce4 4.10
  Reboot.

Try the following:

1. In Settings > Desktop > Menus
 a. uncheck Show applications on right click.
 b. uncheckShow window list on middle click.

2. go to Settings > Desktop > Icons
 select type: None or Minimized

Then this should pretty much disable all interaction with the desktop.

To apply this change system wide, copy changes from your user folder to:

/etc/xdg/xdg-xubuntu/xfce4/xfconf/xfce-perchannel-xml/xfce4-desktop.xml

remove [Suspend] [Hibernate] buttons from the Xfce logout dialog

Been working on Xfce recently.

I would like to share some trick on how to Customize XFCE Desktop, hope these can save your some time.

My build need to remove [Suspend] [Hibernate] buttons from the Xfce logout dialog

To change system wide:
/etc/xdg/xdg-xubuntu/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml

To change for one user:
~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml

Add these at the end of xml file:

Make it looks like:

Starting Ubuntu Xubuntu without the GUI

For Ubuntu 11.10 and higher

Edit /etc/default/grub

vi /etc/default/grub

Find out this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Change it to:

GRUB_CMDLINE_LINUX_DEFAULT="text"

Update Grub:

sudo update-grub

Please notice, you do NOT need to remove / disable lightdm upstart conf, it already does that for you.

lightdm.conf

# Check kernel command-line for inhibitors, unless we are being called
        # manually
        for ARG in $(cat /proc/cmdline); do
            if [ "$ARG" = "text" ]; then
                plymouth quit || :
                stop
                exit 0
            fi
        done

You will still be able to use X by typing startx after you logged in.
